Biotin: Definition, Properties and Cosmetic Applications

What Is Biotin?

Biotin, also known as Vitamin B7, Vitamin H, Vitamin B Factor and Coenzyme R, is a water-soluble vitamin. It occurs naturally in foods such as nuts, liver, soybeans and fish. In cosmetic formulations, biotin is primarily used as a skin-conditioning and hair-conditioning ingredient.

Biotin in Cosmetic Formulations

Biotin is used in a variety of cosmetic products, particularly skin care products and hair conditioners. It can contribute to the sensory properties of a formulation and is used in products designed to condition the skin and hair.

The original A&T Formulation information describes biotin as being used to improve product texture and to contribute to the appearance and feel of hair and skin. It also describes applications related to moisturising and smoothing the skin surface and conditioning brittle nails.

Biotin in Hair Care

Biotin is commonly associated with hair-care formulations because of its use as a hair-conditioning agent. It can be incorporated into products such as hair conditioners and other cosmetic preparations where hair conditioning is desired.

Cosmetic claims concerning hair growth, treatment of hair loss or other physiological effects should be evaluated separately and must be appropriately substantiated and compliant with applicable cosmetic regulations.

Biotin in Skin Care

In skin care products, biotin can be used as a skin-conditioning ingredient. It may be incorporated into formulations where a smoother and more conditioned skin feel is desired.

Its water-soluble nature also makes it suitable for incorporation into the aqueous phase of appropriate cosmetic formulations, depending on the overall formulation design.
